Abstract
An antenna includes a coupling device having first and second coupling plates, e.g. rectangular plates, connected at opposite ends of a conducting bar that acts as a stripline signal feed. A radio-frequency (RF) source may be connected to the conducting bar via a signal feed network. Multiple instances of the device may be arranged vertically in an antenna array assembly to operate together such that the radiation pattern of the antenna assembly is generally directed horizontally. The array may operate to provide a relatively flat azimuthal gain up to 180° across the UHF or VHF bands.
